Gravel driveways are often susceptible to potholes caused by weather-related erosion. A pothole is formed when there is a weak spot in the driveway. This is usually an area where the underlying sand or dirt is exposed. After heavy rains, a puddle settles in this spot and begins to erode the underlying dirt as vehicles drive over the area.
This causes depression to form; the hole becomes deeper and evolves into a pothole. It is important that potholes are repaired when they first appear. Do not wait for them to get large and difficult to fix. There are several methods that can be used to repair potholes in gravel driveways. The method you choose will depend on the extent of the pothole damage and the amount of time and money you would like to spend on repairs.
The simplest way to repair potholes in gravel driveways is to fill the holes with rocks and dirt. To do this you will need a pile of three-inch rocks, dirt or sand, gravel, and a shovel. Using your shovel, scrape any loose gravel from inside each pothole. Then pack the pothole with the three-inch rocks until it is filled to approximately two inches from the top surface. Shovel dirt or sand on top of the rocks. Pack the dirt with the back of the shovel to keep it compacted inside the hole. After the hole is filled with dirt, cover the entire surface of the filled hole with a layer of fresh gravel.
Another option is to mix the three-inch stones with clay. You can use this mixture to fill the hole and then place a layer of gravel on top. Potholes can also be filled with granite sand. This sand is sold at quarries and is gray and grainy in texture. Granite sand is heavy and has the solidity of cement when it is wet. Shovel the granite sand into the pothole. Cover with dirt and then add gravel. The next time it rains, the granite sand will mix with the water and become hard like rock. This will make the pothole repair more permanent and durable.
The concrete ready mix can also be used to fill potholes. Purchase a bag of the concrete ready mix for every two potholes you need to fill. Scrape any loose gravel from the pothole and pour the dry mix into the hole leaving a space of two inches from the top. It is important to leave some space to compensate for expansion. Ensure that the concrete ready mix is packed smoothly and tightly inside the hole. Overlay the dry mix with dirt or sand followed by a layer of gravel. Rain will blend with the dry concrete and it will eventually solidify. You will then have an impenetrable cement filling inside the pothole.
If your driveway has a large number of potholes and you own a small tractor, you can do a much more thorough job to repair the potholes. Purchase a small scraper blade for your tractor. Start at the top of the driveway and scrape the gravel surface slowly in one direction. As you scrape, the potholes will be filled and ruts will be leveled. Ensure that you are crowning the road.
This means that the layer of gravel on the driveway should be higher in the center and lower along the sides. This will also create graded sides that will allow water to run off instead of collecting in puddles. Scraping the entire road will improve the general condition of the surface and make it less inclined to form potholes. It is best to scrape the road a few days after it has rained because the road surface will be softened and easier to grade.
Knowing how to repair potholes quickly and efficiently will make them less of a nuisance. It will also keep your gravel driveway in better condition and reduce the effects of erosion.Knowing how
